HARROW.

Specification of Letters Patent.

Patented June 8, 1909.

Application filed January 19, 1909. Serial No. 473,086.

To all whom it may concern:

Be it known that I, LoRA F. l/VHEnLEss, a citizen of the United States,residing at Vilonia, in the county of Faulkner and State of Arkansas,have invented certain new and useful Improvements in Harrows; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to new and useful improvements in harrows and ismore particularly an improvement over my former patent #887164, issuedMay 12, 1908, and my object is to provide a harrow having teeth whichmay be set at various angles and a further object is to'provide meansfor quickly operating the teeth to dispose them at various angles.

Other objects and advantages will be here inafter referred to and moreparticularly pointed out in the claim.

In the accompanying drawings forming part of this application, Figure 1is a trans verse sectional view through the harrow showing the teeththereof on an inclination. Fig. 2 is a similar view showing the teeth ina vertical position and the draft appliance located at the opposite sideof the harrow from that shown in Fig. 1. Fig. 3 is a sectional Viewshowing the teeth set to enter the soil when the harrow is movedforwardly. Fig. 4: is a perspective View of the harrow complete.

Referring to the drawings in which simi lar reference numerals designatecorresponding parts throughout the several views, 1 indicates aplurality of beams, through each of which are extended a plurality ofteeth 2, and in order to make the beams and teeth therein travel inunison, bolts 3 and 4 are disposed, respectively, through the upper andlower edges of the beams, the bolts having eyes 5 and 6, respectively,which extend on opposite sides of the beams and the bolts 3 of one beamare connected to the bolts 4 of the next succeeding beam by means oflinks 7 said links engaging the eyes of the bolts.

A bar 8 is extended laterally across the beams 1 and is attached at oneend to the outer beam by means of a bolt 9 extending through the bar anda similar bolt 10 extending through the beam, said bolts having eyeswhich interlock with each other and thereby making a pivotal connectionbetween the bar and beam.

The opposite end of the bar is secured to the opposite beam through themedium of a lever 11, which lever is extended through a slot 12 in thebar and is pivoted therein by extending a pin 13 laterally through thebar and slot and through an opening in the lever, the lower end of thelever being pivotally secured to a bolt 14, which bolt extends throughthe beam 1.

The lever 11 is provided with a latch mechanism 15, which is adapted toengage the notches 16 in a rack 17 and thereby hold the lever in variousadjusted positions.

By this construction it will be readily seen that when it is desired tochange the angle of the teeth 2, the lever 11 is to be swung forwardlyor rearwardly, as the case may require and after the lever has beenadjusted to the proper position, the latch is to be engaged with one ofthe notches in the rack and the teeth thereby held in their adjustedposit-ion.

By providing this form of device, the teeth may be quickly adjusted tovarious angles and held in their adjusted positions and this operationmay be performed while the harrow is in motion, if desired.

It will further be seen that this form of harrow may be very cheaplyconstructed and at the same time rendered strong and durable and it willlikewise be seen that the harrow may be quickly adjusted for shallow ordeep cultivation.

I claim:

In a harrow of the class described, the combination with a plurality ofcross beams hav ing teeth attached thereto, bolts passing laterallythrough the upper and lower portions of said beams, each bolt having aneye, the eye of the upper bolts being opposed to the eyes of the lowerbolts and links engaging the eyes of the upper bolts of one beam and theeyes of the lower bolts in the next succeeding beam; of a bar above saidbeams, a bolt passing vertically through one end of said bar, a boltvertically disposed through one of said beams, said bolts havinginterlocking eyes, a lever pivotally secured adjacent the opposite endof said bar, a bolt passing vertically through the beam below the leverengaged end of the bar and having an eye with which the lower end of thelever engages, a rack on the bar and means carried name to thisspecification in the presence of l L 1 ,7 by the lever adapted to engagethe notches 1 HEELhSb' "W0 subscribing witnessea.

5 in said rack and hold said lever and parts l/Vitnesses:

attached thereto in their adjacent positions. A. J. .MOORE,

In testimony whereof I have signed my NV. F. Tnomssox.
